Abstract: An anti-reflection film (X) of the present invention includes a laminated structure including a substrate (11), a hard coat layer (12), and an anti-reflection layer (13). The anti-reflection layer (13) contains a curable resin, low-refractive-index particles, and nanodiamond particles. The anti-reflection layer (13) may further contain a fluorine-containing curable compound. Such an anti-reflection film is suitable for achieving high scratch resistance together with high anti-reflective properties.
